The Book's Physical Form Matters
- The book's physical form (the hardware) shapes how we use and benefit from its content.
- Augustine's marking a passage shows format enabled reflection and comparison impossible with scrolls.
Augustine's 'Marked' Conversion Moment
- Augustine's conversion hinged on opening Paul's letters at random in a codex and marking the passage.
- That small, physical act reshaped his life and later influenced Luther and Wesley.
Medium Shapes How Texts Are Read
- The medium shapes interpretation: order and format influence which texts get priority.
- Bible apps and searchable interfaces encourage cherry-picking over sequential narrative reading.
